Claims. (01. 189-64) This invention relates to detention windows and in more particular to a detention window assembly wherein the conventional guards, having detention bars supported in fixed relation by a 5. plurality of rail bars, form the support for the glass either directly or indirectly.

An object of this invention is to produce a window that is cheap, easily constructed, very efiicient in preventing the escape of human bodies 10 through the window and at the same time presenting a neat appearance.

Another object of this invention is to provide glass supporting members interlocking with the guards to permit easy construction of the window assembly, resulting in a substantial permanent structure.

Another object of this invention is to provide supporting members for the glazing transversely arranged with respect to the glass supporting 2 muntins, concealing detention bars.

Another object of this invention is to provide a removably mounted member cooperating with other glass supporting member to hold the glazing in position.

Another object of this invention is to provide a closure for the ventilating area found inthe guard window assembly, the closure being separated from the metallic parts of the guard except for the necessary connection which may be accomplished by placing mounting means intermediate the guard and the closure.

Another object of this invention is to space the parts of the window structure from the guard as far as possible to prevent corrosion.

With the above primary and other incidental objects in view, as will more fully appear the specification, the invention consists of the features of construction, the parts and combinations thereof, and the mode of operation or their equiv-.- alents, as hereinafter described and set forth'in the claims.

This application is related to my copending ap- 5 plication SeriallNo. 687,323 filed August 29, 1933,

Patent No. 2 ,020,046,granted Nov. 5, 1935. In my copending application the glazing extended across the entire window assembly. The glazing is supported upon members extending parallel to the rail bars of the guards. In the present embodiment the window supporting members extend parallel to the detention bars, so as to conceal the same, except across the ventilating area.

The glass supporting members aligned with the detention bars are preferably T-shaped, having the flanges notched, so as to fit over the edges of the rails, the reby holding the glass supportin m m e in a ri id. co c relation with resp c o the uard t s m of the p d bars extending between the window panes. Adiacent to the ventilating area of the stems of the T-bars have preferably been notched, so as to accommodate the glass supporting members ound n t e e tilating area Referring to the drawings the detention bars l0, having the opposite ends embedded in the masonry honnding the ventilating area, are held in spaced relation by a plurality of parallel rail bars 12, also having their ends embedded in the masonry. Although the rail bars and detention bars have been shownas embedded in the wall surrounding the window opening, the detention bars and rail bars may be otherwise held in position. In the modification disclosed the detention bars are passed through holes provided therefor in the rail bars. The detention bars Ill may be provided with ribs M, for interlocking the rails in position, as is well known to those skilled in the art. 1

U The glazing l6 extending over a portion of the guard, issupported upon T-bars 18, having their flanges notched at 20, so as to fit over the margin of the rail bars. The T-bars I8 are preferably aligned with respect to some of the detention bars, sov as to conceal the same, thereby eliminating the objectionable appearance of these detention bars. The stems 22 of the T-bars I8 separate the window panes. .The stems are preferably notched at 24 and .26, so as to accommodate the transversely arranged glass supporting members 28 and 29, respectively.

The glass supporting member 28 shown in Fig. -2,is a portionofthe frame of the closure assembly 30 extending over the ventilating area. The T- bars it, which constitute muntin bars for the fixed glazing and .the closure 30, are held in position by members 32, havingholes receiving the deten- .tion' bars l0 and suitable flanges 34 that aresuitably securedin position. Thus, it will be seen that theT-bars or muntin .bars l8 interlocking the rail bars I2, which are seated in the notches 2!] and the closure frame 30, are held in a rigid unitary structure by members 32. The glass sup porting flanges 28 and the muntin bars I8 form three sides of the glass supporting means. The fourth side of the glazing is held in position by the glazing strips 29, which may be flat bars having holes receiving thef'studs 36, welded or otherwise attached to the stem 22 of the T-bar 18.

The strips 29 may be held in position by nuts 38' threadeclly engaging the studs 36 In the modification disolosedin Figs. 1, 2, and 3, the closure 3!! for the ventilating area has been mounted on the same side of the detention bars as the glazing l6. Referringto Figs. 4 and 5 the closure assembly 30 has been mounted on the side of the detention bars opposite the glazing IS. The closure may be attached to the detention bars It in any suitable manner for example, the retaining members 32 as shown in Fig. 4. In this modification angle bar '4U,having the flange 42 secured to the structure and the flange 44, is arranged to form a" seat for the glazing I6. The space intermediate the muntin bars bounding the ventilating area .and closure frame disposed in the opposite side of the detention bars may be closed'in any suitable manner, as by a metallic member 3|.

In each of these modifications the glazing l6 extending along the bottom or the sill of the window is preferably held in position by putty, providing water-tightness between the lower rail l2 and the masonry surrounding the window. In order to prevent water coming in at the closure, water-shedding members 46 and 48 respectively are provided adjacent to -the closure in any suitable manner.

In the modification shown in Fig.4 a screen 50 is mounted in aligned relation with the glazing 16. The screen includesa frame 52 suitably attached to the window assembly.

In view of the fact that it may oftentimes be desirable to have a closure for the ventilating area that is higher than the'distance between the two adjacent rails l2 in the normal guard assembly, one or more'of the rails l 2 may be omitted across the ventilating area and rail bars 54 of a different cross sectional area, preferably welded to the detention bars [0, may be used to support the detention bars in a fixed spaced relation. The rail bars 54 may be spaced closer so as to give additional protection to the more vulnerable areas of the window assembly. These bars 54 may be mounted upon the side opposite the closure, so that when the closure is mounted upon the same side of the detention'bars as the glazing IS, the

rail bars 54 will be mounted upon the opposite side of the detention bars. If the closure is mounted upon the opposite side of the detention bars from the glazing IS, the rail bars are preferably mounted upon the same side as the glazing. The spacing of the glazing l6 and th'e'closure 30 from the rail bars and the detention barspermits washing of the glazing, both in the free areas and the areas intermediate the glass and the detention and rail bars. This has been found to be a very desirable feature. w

In all of the above modifications themetallic parts subject to corrosion are separated as far as consistent with the utility. The spaces intermediate adjacent. metallic parts are, wherever feasible, sealed with putty or other suitable sealing material. Where this is not done, it has been found verydifficult to prevent adjacent metallic members from rusting, asit is almost impossible guard, the muntin bars and the closure may have the exposed portions painted, the parts being so constructed and arranged as to permit the separation of the parts by paint or sealing the juncture to eliminate rusting.

Although the T-bars have been shown with notches the T-bars may extend continuously across the guard either in off-set relationship or seated in seats provided therefor in the guard assembly.

The glazing may be mounted on either the outside or' the inside of the glazing depending entirely upon the demands.

From the above description it will be apparent that there is thus provided a device of the character described possessing the particular features of advantage before enumerated as desirable, but which obviously is susceptible of modification in its form, proportions, detail construction and arrangement of parts without departing from the principle involved or sacrificing any of its advantages.

While in order to comply with the statute, the invention has. been described in language more or less specific as to structural features,- it is to be understood that the invention is not limited to the specific features shown, but that the means and construction herein disclosed comprise the preferred form of several modes of putting the inventioninto elfect, and the invention is therefore claimed in any of its forms or modifications within the legitimate and valid-scope of the appended claims.
